Question

Veronica walks dogs in her neighborhood for extra money during the summer. For each dog walk, she earns $5.25. On Monday, she completes 3 walks, and on Tuesday she completes 2 walks. She estimates that in order to save up for a new purse that costs $86, she needs to complete 12 more walks by the end of the week.

Is Veronica's estimate reasonable? Why or why not?


Responses


Yes, because 5 is very close to 5.25 and 85 is very close to 86, but 5⋅(3+2+12)≠85.


Yes, because 5 is very close to 5.25 and 85 is very close to 86, and 5⋅(3+2+12)=85.



No, because 86 divided by 5.25 is not exactly 3+2+12.


Yes, because 86 divided by 5.25 is exactly 3+2+12.

Answer 1

No, because 86 divided by 5.25 is not exactly
`\(3 + 2 + 12\)`.

Explanation:

Veronica earns $5.25 per walk. She completed 3 walks on Monday and 2 walks on Tuesday, and she estimates that she needs to complete 12 more walks by the end of the week. That totals
`\(3 + 2 + 12 = 17\)` walks.

If she completes 17 walks at $5.25 per walk, she would earn
`\(5.25 * 17 = $89.25\)`, which is more than the $86 she needs for the new purse.
